35 amps of current goes through a 40 amp fuse. What happens?
25 amps of current goes through a 15 amp fuse. What happens?
Think about what a fuse is used for. Why would you put a fuse in a circuit?
A fuse is a protective device used in electrical circuits to prevent damage to the circuit and connected devices in the event of an excessive current flow. It is designed to break or "blow" when the current exceeds its rated value, thereby interrupting the flow of electricity.
In the first scenario, where 35 amps of current goes through a 40 amp fuse, the fuse will not blow because the current flowing through it (35 amps) is below its rated value (40 amps). The circuit will continue to function normally.
In the second scenario, where 25 amps of current goes through a 15 amp fuse, the fuse will blow because the current flowing through it (25 amps) exceeds its rated value (15 amps). When a fuse blows, it breaks the circuit and stops the flow of electricity, protecting the circuit and devices from damage. In this case, the fuse will need to be replaced with a new one of appropriate rating before the circuit can be restored.
A fuse is a safety device used in electrical circuits to protect the wiring and components from excessive current. Its purpose is to break the circuit and prevent any damage or potential fire hazards caused by overcurrent.
In the first scenario, where 35 amps of current goes through a 40 amp fuse, the fuse will not blow or break the circuit. This is because the current passing through the circuit is below the amp rating of the fuse. The fuse is able to handle and allow the current to flow safely without any issues.
In the second scenario, where 25 amps of current goes through a 15 amp fuse, the fuse will blow or break the circuit. This is because the current passing through the circuit exceeds the amp rating of the fuse. When this happens, the fuse will melt or blow, creating an open circuit and stopping the flow of current. This is a protective mechanism to prevent the wiring or components from getting damaged or overloaded.
To determine what happens in different scenarios involving fuses, you need to compare the current (amps) passing through the circuit with the amp rating of the fuse. If the current exceeds the amp rating, the fuse will blow and break the circuit. If the current is below the amp rating, the fuse will allow the current to pass through safely. It's important to choose an appropriate fuse rating that matches the maximum current that the circuit can handle to ensure proper protection.
